Earth is many thousand kilometers in depth. If you could travel deep into the earth's surface you would find that it contains three main layers; the crust, mantle and core. To learn more about the layers of Earth, click the following links and answer the questions that follow. Go to The Earth's Interior
How is Earth's interior like an apple?
The lithosphere is divided into 2 parts (or crust).
Click on the Volcano World link. After reading each slide click the "next" button and proceed to read the next slide. When you have examined all of the slides, complete the questions on the "questions" slide. These questions are also below.
Name the five layers of the earth in order from the outside to the center of the earth.
What causes the mantle to "flow"?
What are the two main metals that make up the outer and inner core?
Describe in your own words how the earth's layers were formed. (Slide 2 will help you.)
Part 2: Convection Currents and the Mantle - worksheet 2
Heat transfer is the movement of heat from a warmer object to a cooler object. There are three ways in which heat can be transferred; conduction, convection and/or radiation. Click on the links below and answer the questions that follow.
If air is a fluid, why isn't convection responsible for transferring heat to Earth from the sun?
Test your knowledge! Scroll back to the top of the Heat Transfer Web page and take the "Mini Quiz".
As you already know, the earth's mantle contains two layers; the stratosphere (tough liquid part of the outer mantle) and the lithosphere (the stiffer outer mantle and the crust). Because of the intense pressure and temperature in the mantle convection currents occur. To learn about what influence these convection currents have on Earth, read the Web page below and answer the questions that follow.
